Thisinventien relates to valve seat: pullers or implements for alike purpose, and the genwhich may beeasily applied, and whieh is thoroughly effective in act-ion.

1 I i My invent-ion is illustrated in the accompanying drawing, wherein I a Figure liis aside elevation of a valveseat puller; constructed in accordance with my invention, one. of the links being removed j'iI ISG CtiOI ILn a 7. pp 1 "Figure 2 is a. section on the'line 2-2 of F ur i Referring to thisdrawing '20 and the pivot pin forthelever being shown It) designates a pair ot links Eaeh of these links at. its

lower end is rovided with anopening 11 .eonstituting t e bearing: jiiQI the trunnion gtagliftingblock, ilSQ-Vllll later stated.

i- A djacent the upper end; ofithe links there are provided aplnrality of openings 12 for :the reception of transverse pin 13, this 1 pin'having cotter pins at its extremities iwhereby it may be held inmplace. I

Mounted upon this pin 13 and oscillating upon the pin is a lever 14 which is provided with an opening lz' sthrough whichthe pin. 13 passes the lever-having a fl t IOWQI" f c i bar adapted to be d sposed across the nouth of. i a valve chamber, links disposed on each of the cross b313 3 lever llQLWlliCllthB upperends of the links are attached, alvalve andits upper face extending downward and towardthe rear end olj the lever, The thickened or free endof the lever is formed with a nose 16 'and the opposite end of the lever is formedjwitha. sorew-threaded bore 17 and through this bore passes an adjusting sereWQ IS having mea ns -at its upper end whereby it may be turned, the lower end of this adjusting screw being rounded.

v Mountedupon a trunnion or pin 19 is the lifting block 2() which is approximately elliptical in form and provided withzthe two outwardly projeeting teeth or shoulders 21 ,vvhich are adapted to engage'beneath a valve seat A, as shown in' Figure 1; This lifting bleak may be turned into; a position nearly parallel to the links IOfor insertion through the valve opening and then turned :to a

transverse position-beneath the valve seat,

as shown in Figure-1?. i

. The linksilt) are; designed to be disposed on each side of across bar 22 designed to extendoverthe mouth of the valve chamber-B and rest uponthe margins of Said rnouth is-shown in Figure 1:." This cross bar is preferably about fourteen inches long, one inch thick and four inches Wi e; and the l nks- 1 0are about; twenty-two inches long. The rotation of the screw 18 forces the point of thi-s-screwqdownward in a seat 23 o m in n n o the G os bar an hi forees the nose 16 downagainst thecross bar and exerts;i of course, a: very great lifting force uponthe links 10 thus pulling the i valve; seat from its normal positioni-The valve seats in a pump only haveto be pulled about and they come loose, as theyhave l considerable taper. It is, therefore not necessary, where this device is designed for the pulling. of pump valve seats, that the linkslO shall have a great amount of movement but V itiis necessary that the device should have very great power, andthat is precisely what is sec urediin this device,

Qbviously this valve seat puller. mightbe constructed of difierent c liinensions and proportions 7 for use under different circum staneesflandgit is-likewise vobvious that a. number of the lifting'blocks QOn ight be ply beneath the valve seat itself andnot with the wall surroundingthe' valve seat.
